Predictors of adherence, contamination and dropout in home‐based walking by lung and oesophageal cancer patients from two randomised control trials: An exploratory study

Abstract

Objectives In this study, we examined predictors of exercise adherence, contamination and dropout in lung and oesophageal cancer patients who participated in two randomised controlled trials. Methods We used data on 188 lung and oesophageal cancer patients from two previous studies (intervention: moderate‐intensity walking for 12 weeks). Baseline measurements included demographic variables, disease characteristics, Hospital Anxiety and Depression Scale and Bouchard 3‐day physical activity (PA) record. We used multiple linear and logistic regressions to analyse predictors of exercise adherence in the walking group, contamination in the control group and dropout in both groups. Results Pre‐intervention exercise habits and baseline depression scores predicted adherence, with an explanatory power of 16.7% (p < 0.0001). Pre‐intervention exercise habits (odds ratio [OR] 19.65, 95% confidence interval [CI] 2.76–139.97), baseline moderate PA (min/day) (OR 1.03, 95% CI 1.01–1.05) and baseline vigorous PA (min/day) (OR 1.09, 95% CI 1.01–1.18) predicted contamination. Baseline mild PA (10 min/day) (OR 0.94, 95% CI 0.89–0.99) predicted dropout. Conclusions Pre‐intervention exercise habits and baseline depression levels predicted exercise adherence in the walking group. In the control group, pre‐intervention exercise habits and baseline moderate and vigorous PA predicted contamination. Baseline mild PA predicted dropout rates in both groups.

Association of Frailty and Depressive Symptoms With the Establishment of Exercise Habits in Patients Undergoing Outpatient Cardiac Rehabilitation

“… 14 On the other hand, studies involving cancer and patients with chronic obstructive pulmonary disease have reported a correlation between high depressive symptoms and poor exercise adherence. 22 , 23 However, a study focusing on 73 smokers with a history of alcohol dependence found that the attendance rate in exercise sessions for respiratory rehabilitation was similar between the depressed group and the non-depressed group. 24 Consequently, there is no consensus on the effect of depressive symptoms on subsequent exercise adherence.…”
